This problem concerns the second order network shown below. When the network is excited by a sinusoidal current of the form i_S = I_s \cos(\omega t), where I_s = 10 {\rm mA}, the magnitude of its common voltage v_C as a function of frequency is as shown graphically below. Note the units used for frequency in the graph. Use the graphical information to answer the questions that make up this problem, and note that these magnitudes are plotted on a linear scale, not on the log scale that we're used to.
Determine R, L, and C. Numerical answers should be in Ohms, Henries, and Farads, respectively.
Shown below are a set of possible graphs of the phase of the common network voltage vC as a function of frequency. Select the correct graph in the multiple choice below:
Shown below are a set of graphs of the common network voltage v_C that might result from a step in the current i_S such that i_S = Iu(t) where I = 100 mA. Select the correct graph in the multiple choice below:
